FURNACE.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Original application filed September 28, 1904, Serial No. 226,380. Divided and this application filed February 6. 1905. Serial No. 244,494-

I To (I/ZZ 10 1/0122, it T/bm/j concern:

Be it known that I, JAoINTo RODRIGUEZ Y FoNoLL, a citizen of the Island of Cuba, residing at Boullon N o. 31, city of Cienfuegos, Cuba, have invented a new and useful Furnace, of which the following is a specification.

This invention relates to improvements in furnaces, and particularly to steam-boiler furnaces.

The principal object of the invention is to provide a novel form of steam-boiler furnace in which the grate as a whole is mounted on a truck which may be readily withdrawn from the combustion-chamber and, if necessary, reversed and replaced within said cham- A further object of the invention is to provide a device of this class in which the entire fire-grate may be readily removed for the purpose of tending to the fire more conveniently or for necessary repairs to the grate, and, further, to permit the removal of the grate should it be necessary to repair the bridge-wall or other portions of the furnace accessible from said combustion-chamber.

lVith these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of con struction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a perspective view-of a portion of a steamboiler furnace provided with a removable and reversible grate constructed in accordance with the invention. Fig. 2 is a sectional elevation of the wheeled grate. Fig. 3 is a side elevation of a portion of the wheeled grate.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the draw mgs.

The present application is a division of an application for patent for improvements in boilers filed by me on September 28, 1904, under Serial No. 226,380.

The furnace is provided with a suitable front Wall and a bridge-wall 13, as shown, and in the bottom of the combustion-chamber is arranged a pair of rails 25, that extend outward on the floor of the boiler-house and lead to similar rails on a small turn-table 26, that is arranged in a pit at the front of the boiler. On these rails is mounted a wheeled truck 27, carrying a grate 28, the latter being of any suitable construction in accordance with the character of the fuel to be employed.

In operation the lower doors of the furnace are opened, and the truck may be pulled out to permit the raking or slicing of the fire or the removal of clinkers, and, if necessary, the truck may be run onto the turn-table 26 and its position reversed end for end before being returned to the combustion-chamber, thus permitting of the thorough combustion of the fuel. It will also be found highly advantageous in that the grate may be thoroughly cleaned and repaired, and the bridgewall and other parts of the furnace will be accessible without rendering it necessary for the firemen to crawl over the grate-bars, as at present practiced, when immediate repairs are necessary.

It will be noted that the grates are supported by brackets 30, having flanges 31 ex tending over the wheel-treads and their in nor faces being inclined and forming guards for the axle-boxes.

Having thus described the invention,what is claimed is 1. In furnaces, a combustion-chamber, a bridge-Wall, a wheeled grate arranged in the combustion-chamber and reversible to place either end adjacent to the bridge-wall.

2. In a heating plant, a furnace including a combustion-chamber, a turn-table arranged on the floor of the fire-room, and a wheeled grate movable between the combustionchamber and the turn-table, the latter serving as a means for reversing the position of the grate.

3. In a heating plant, a furnace including a combustion-chamber, a turn-table arranged on the floor of the fire-room and provided with rails, rails leading from the edge of the turn-table to a point within the combustionehainber, and. a wheeled grate arranged 011 the rails, the turn-table serving as a means 5 for reversing the position of the grate to present either end adj aeent t0 the rear Wall of the COIDbUStiOH'OhQIHb61.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
